T0 00 whom, it nmy concern:

Be it known thatwe, JOSEPH N. MORROW county of Vanderburg and State of Indiana, have lnvented certain new and useful Improvements in Dimension Gang-Edger for Cutting Dimension Lumber; and we do here by declare that the following is a full, clear, and exact description of the invention,which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which forms. part of this specification.

' Our invention relates to certain new and useful improvements in saw-mills, and relates more particularly to that class known as gang-edgers for cutting dimension lumber; and it has for its object to provide means whereby the dimensions of the lumber and the speed with which it is supplied to the saws may be regulated.

Our invention to accomplish these. purposes consists of a spline-shaft having saws movable thereon by means of levers, whereby they may be caused to approach or recede, and of disks the periphery of one of which bears upon the face of the other, the distance of the point of contact from the center of the latter disk being capable of being changed at will, whereby the speed of the feed may be increased or decreased, and in the necessary parts to secure the proper interaction and dependency between these features, and in other details of construction, as will be hereinafter fully described and claimed.

Referring to the accompanying drawings, in which corresponding parts are designated by similar letters, Figure 1 is a plan View of our invention with the rod K and lever Q broken away. Fig. 2 is a side View taken on the right-hand side thereof. Fig. 3 is a side view taken on the left-hand side thereof. Fig. 4 is a front view, and Fig. 5 a rear/view, thereof. Fig. 6 is a detail longitudinal elevation showing the saws and saw-adjusting mechanism detached from the body of the machine.

Fig. 10 is a detail of the mechanism. for varying the motion transmitted to the feed-rollers. Fig. 11 is a detail of one of the plates h, showing the lug h thereon. Fig. 12 is a detail of the hanging frame. Fig. 13 is a detail plan view'of the saws, saw-arbor, and guides; and Fig. 14 is a seriesof saw-guides detached and separate. "A suitable framework A of the ordinary character-has formed upon one side thereof (the right-hand side in the drawings annexed hereto) an extension frame-work A, having bearings a a formed thereon and upon the opposite side of the main frame-work A to receive a spline-shaft B and an extension thereof B. The main driving-pulley O, to which motion is imparted in any suitable manner, is mounted half upon the shaft B and half upon the extension B, being secured to the former by bolts 0, and being permanently attached to the latter. By this construction saws may be placed upon and removed from the shaft B without removing pulleys or belting, as when the bolts 0 are loosened and the extension B and pulley (J are moved outward the latter is by the slightlateral movement drawn off the shaft B and permit ted to fall upon boxing within the extension A, thus freeing the end of the spline-shaft.

A circular saw D is fastened permanently on the shaft B in the usual manner and steadied by a fixed guide d, while circular saws D are mounted upon the shaft and adapted to be moved laterally thereon by means of guides E, located beneath the bed of the machine. Each of these guides consists of two arms-e e, uniting at a different angle for each of the guides, the arms 6 being slotted to receive a portion of the forward lower quadrant of the saws. A bar E passes through all of the guides at or near the junction of the two arms of which they are composed, and is attached to the upright frame A at 6 while the arms e of each of the said guides are of different length and work upon independent bars E fastened to the frame A, each of the said bars E being at a different level and on a different vertical plane under the bed of the machine, this being permitted by the different angles made by the. arms e and e and by the difference in the roo of the corresponding saw, the link f permit-v ting the guide to move on a straight bar E, while the movement of the rearend of the lever is in the arc of a circle. To secure the levers in the exact position in which they may be placed, the forward end of each lever has a longitudinal slot f in the top thereof, in which a rsgedge f? is caused to move forard 9. ba kw r by the a t on of e U- her d pie f pivoted to he b tom f he I o ward end o h ever and t th t n o h forward end of the ned The bottom,

For i l l l g t kn sef he ab er board cut by the immovable end saw D, we use i a sliding guide H. This guide consists of a h Pi ce 1, o suitable mat ria ha n p a h, provided with lhgs or projections h on their lower surfaces at both of its ends, the said projections of each plate moving in equally-inclined diagonal grooves h cut or formed upon the frame A, so that any move- 1 ment of the piece it toward the front or rear of the machine causes it to recede from or approach the center of the saw-bed, and thus I to cause a greater or less width of lumber to be cut by the end saw D. The slide-piece h is adapted to be moved forward or backward by the handle it, attached to the rod hi, which has teeth formed upon its under surface and adapted to engage a lip 71;", formed upon the frame A. The said teeth may be so graduated as to show the thickness of the board made by the end saw, and thus serve both as a measure and as a means for holding the,

sliding gage in the required position.

In order to vary the speed of the feed, we construct a vertical framework A u )on the main frame-work A and extension A to provide supports and bearings for the hereinafterdescribed mechanism. The free end of the Shaft B, upo w i is ount t e i driving-pulley C, and which extends beyond the extension frame-work A, acts as a pulley to impart motion by means of a belt and wheel I to a disk I, mounted upon a shaft 1 running partially across the machine. A seconddisk J is firmly fixed upon the splineshaft J, running at right angles to the shaft 1 and which has also mounted thereon a gear-wheel J secured in a fixed position in relation to the frame A by means of a brace J while the shaft itself is adapted to be moved in a longitudinal direction by the hereinafter-described means, thus causing the point of contact between the disks I and J to vary to a point either farther or nearer the circumference of the former, and causing a corresponding decrease or increase in the notation of the latter and of the shaft upon which it is mounted, as well as of the gear,- Wheel J The longitudinal motion of the shaft J is effected by means of a handle K, pivoted at its middle, while to its upper end is attached one end of a bar K, ,while the oth r end of the Sai bar is attached to a lever K pivoted at its center to a bracket A projecting from the frame-work A while the lower end ,of the said lever is attached to the shaft J, Thus a movement of the lower part of the handle toward the rear of the machine wi cau e t eerr pond hs mot n .of h sk J and an increase in its speed. The outer end of the shaft 1? bears against a bracket A, attached to the framework A This bracket is adapted to be drawn inward by means of a bolt a provided with a nut ai'cansing the diskl to hear more firmly upon the periphery of the disk J.

A shaft L, carried in bearings Z upon the f meo k eishtensle t0 the Shaft has upon its inner end agear-wheel L, meshing with the wheel J- while upon its outer end is the pulley L, which ,drives by means ,of a belting M, passing around the take-up rollers N and N, journaled in the framework A, the pulley O, mouuued upon one end of the shaft ,O,running transversely through h f me-w rk At hile p n h t r end thereof is Secured the pulley 0?. A shaft P, having pulley Pon one end thereof and a feedroller P in the middle portion, is hung in a ICC frame-work P upon the shaft 0, and is adapted to be raised or lowered by means of the stirrups or bars Q, attached to a levenQ, passing above the machine to the front end thereof. A belt B passes over the pulleys O? and P, and is kept at a constant tension by means of the hanging frame P and imparts a motion to the feed-roller P7 which communicates it to the lumber supplied to the saws in the usual manner, the speed of the feed of which depends upon the relative position of the disks J and I to each other and upon the position of the feed-roller PF, which may. be varied and placed at different heights above the anti-friction rollers G by means of the lever Q and rods (31' stirrups Q.

It will be thus seen that the position of the 'saws'to each other and to the frame-work and 1.
